This alarm occurs when there are multiple call failures due to the lack of bandwidth for a call on a particular location. While the alarm is active, the system checks the number of calls denied through a particular location within a particular interval, with a one hour default. The alarm is cleared when no calls were denied for the location within the last interval.

This event may be caused by one of the following:

• More simultaneous call traffic than anticipated at a specific location.

• The provisioned bandwidth for a specific location is insufficient for the actual carried traffic.

• The provisioned bandwidth for a specific location is correctly set according to LAN characteristics. However, traffic exceeds actual network capacity.

• Inappropriate bandwidth limitations.

• Network issues.
